Planning Permission in Guildford
Non-Metropolitan District in South East · Last updated April 2026
Guildford is Surrey's county town, centred on a historic High Street that climbs steeply from the River Wey to the castle and cathedral. The borough extends into the Surrey Hills AONB and extensive Green Belt, encompassing villages like Shere, Chilworth, and the Horsleys. The University of Surrey campus and the Royal Surrey County Hospital add to the town's character.
With 41 conservation areas, Green Belt covering much of the borough, the Surrey Hills AONB, and 1,089 listed buildings, Guildford balances urban vitality with countryside protection. The council approved 85% of applications in the year ending September 2025.
This guide covers permitted development rights, planning fees, and the application process for homeowners across the Guildford borough — from the town centre to the Surrey Hills villages and Green Belt countryside.

Permitted development in Guildford
Guildford's planning context combines urban Guildford with extensive Green Belt and the Surrey Hills AONB. Green Belt properties must ensure extensions are not disproportionate. AONB properties have reduced PD limits. The 41 conservation areas restrict development in the town centre and numerous villages. In Guildford's urban residential areas outside conservation areas, standard PD rights generally apply. The council's design expectations are high throughout the borough.

Planning application statistics
Year ending September 2025 | Source: MHCLG planning application statistics
Guildford received 1,449 planning applications and decided 1,284 in the year ending September 2025. The approval rate of 85% is below the national average of 86.9%. Major applications are expected to be decided within 13 weeks, while householder and other non-major applications have an 8-week target. The “in time” figures include decisions made within agreed extensions of time.
Guildford processed planning decisions with an 85% approval rate in the year ending September 2025. The slightly below-average rate reflects the Green Belt, AONB, and 41 conservation areas that constrain development across much of the borough. Well-prepared applications that respect the context generally succeed.
If your project complies with permitted development rules, you don't need to worry about approval rates — a Lawful Development Certificate is a factual assessment, not a judgment call.

Housing delivery in Guildford
Housing Delivery Test 2023 measurement | Source: MHCLG
Guildford delivered 2,300 homes against a requirement of 1,499 over the three-year measurement period, giving a Housing Delivery Test score of 153%.

Lawful Development Certificates in Guildford
A Lawful Development Certificate (LDC) is formal confirmation from Guildford that your project is lawful under permitted development rules. It is not legally required before you build, but it is the only official document that proves your project did not need planning permission. Most solicitors will ask for one when you come to sell, remortgage, or insure your property.
Guildford decided 779 householder applications in the year ending september 2025. Their 8-week performance of 92.3% is below the national average of 93%, so LDC applications may take longer than the 8-week target. LDC applications follow the same 8-week statutory determination period as householder planning applications.
How to apply for an LDC in Guildford
You can apply for a Lawful Development Certificate through the Planning Portal or directly through Guildford's website. You will need to submit:
- A completed application form (available on the Planning Portal)
- A site location plan at 1:1250 or 1:2500 scale
- Existing and proposed floor plans and elevations
- A written description of the proposed works and how they comply with the GPDO 2015
- The application fee of £258
Guildford must issue a decision within 8 weeks. If the application is approved, the certificate is a permanent legal record that the development is lawful. If refused, you can appeal to the Planning Inspectorate or amend your project and reapply.
